SHEET-METAL ARTICLE.

Specification of Letters Patent.

Patented Aug. 8,

To (1H 20 71 0 m it may concern Be it known that i, FRANK E. BAYER, a citizen of the United tates residing at Erie, in the county of Erie and State of Pennsylvania, have invented new and useful improvements in Sheet-Metal Articles of which the following is a specification.

This invention relates to structural features of sheet metal articles and as exemplified are applied to a waste basket. The invention involves a corner construction in which a corner rib is secured to the sides of a corner and by means of the fold the fastening devices are covered. Other details will appear from the specification and claims.

The invention is illustrated in the accompanying drawings as follows Fig. 1 shows a side elevation of the basket.

Fig. 2 a section of a fragment of the sides and bottom with the joint in process of formation.

Fig. 3 a fragment of a side and bottom showing the completed joint.

Fig. 4: a section on the lines l-4 in Figs. 1 and 5.

Fig. 5 a side elevation of a leg bottom.

6 a section on the line 6-6 in Fig. 1.

Fig. 7 a structure showing a corner rib in process of construction.

Fig. 8 shows a form of side blank.

Fig. 9 a corner construction of the top head.

1 marks a side of the basket, 2 the bottom of the basket. I; the top bead, la corner rib terminating in legs. and 5 a leg bottom. The sides are united by a folded joint one side having a return bend. 7 and an. adjacent side having an inward bend 6 extending along the return bend and a hack fold 8 arranged within the return bend.

The bottom is secured to the sides in the manner shown in Figs. 2 and 3. The sides have a return bend 9 and an inward bend 10. The bottom has a return. bend 11 which is hooked into the loop formed by the return bend 9.

The blank of the side has a slight projection 12 at its upper end formed by a notch 13 and the edge portion 14 is turned to form the connection between the bends 6, 7, and 8. The upper edge of the side is turned over a core 15 forming a bead. he folds form a bead 16.

Corner ribs are provided for the basket. These make a finish at the corner and stiffen the receptacle as a whole and improve its appearance and by extending them form for the basket. The corner piece has the attachin edges 19 which are secured at the sides or the corner by spot welding. Even spot welding mars the surface so as to interfere with the proper finish of an article of manufacture. The corner rib has an initial shape as shown in section in Fig. 7. The basket is placed on a horn 20 and a die 21 crowds down the corner rib giving it a completed shape as shown in Fig. 6. With the return fold covering the edge portion 19 and the outer bend 22 forming a finish along the edge of the rib the outer bend or turn 22 should be beyond the edge of the part 19 and is slightly bent inwardly into contact with the side.

In order to finish the bottom of the legs so that they will not mar the floor or catch in rugs a beaded bottom piece 23 is provided.

What I claim as new is 1.. An article of manufacture of sheet metal having sides forming a corner; and a corner rib having its edges secured directly to the sides at the sides of the corner the edges facing outwardly and a reversed loop having folds extending outwardly over the portion secured to the sides.

52. An article of manufacture of sheet metal having sides forming a corner; and a corner rib having its edges seem-ed directly to the sides at the sides of the corner, the edges facing outwardly and a reversed loop having folds extending outwardly over the portion secured to the sides and extending beyond the edges.

An article of manufacture of sheet metal having sides forming a corner; and a corner rib having its edges secured directly to the sides at the sides of the corner the edges facing outwardly and a reversed loop having folds extending outwardly over the portion secured to the sides and extending beyond the edges and into contact with the sides.

at. An article of manufacture of sheet metal having sides forming a corner; and a corner rib having its edges secured directly to the sides at the sides of the corner the edges facing outwardly and a reversed loop having folds extending outwardly over the portion secured to the sides, the rib being spaced from the corner at points nearer the corner than the edges.

5. A basket formed. of sheet metal and having sides forining'corners; and a corner rib having its edges secured directly to the sides at the sides of the corner, the edges facing outwardly and a reversed loop having folds extending outwardly over the portion secured to thesides.

6. A basket formed'of sheet metal and having sides foriningcorners; and a corner yond the edges.

7 A basket formed of' sheet rnetal vand having sides forming corners; and a corner ribhaving'itsedges secured directly to the tion. secured to the sides and extending beyond the edges and lnto contact with the sides.

8. An article of manufacture of 7' sheet to the sides at the sides of the corner, the

edges facing outwardly and a reversed loop having folds extending outwardly over the portion secured to the sides, the corner'rib being extended forming legs for the basket. i

In testimony whereof I have hereunto set my hand. n 1
